| GENERAL DESCRIPTION |
 |
The 6961 / TBL7/8000 is a forced air-cooled triode designed for use in industrial RF generators and communication transmitters. The 6961 / TBL7/8000 features an exclusive specially processed grid which makes possible its high grid current rating and overload characteristics. This is particularly desirable in heavy-duty, industrial applications. The filament is thoriated tungsten. Maximum ratings apply up to 30 megacycles. |
